SAMUEL a Brianne, or rr'rrsnunen, PENNSYLVANIA.

Application filed December 8, 1913. Serial No. 835,421.

To all whom it mag concern: v

Be it known that I, SAMUEL A. BENNER, a citizen of the United. States, and resident of 1 Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Car Parts; and I do hereby declare the following .to be a full, clear, and exact description thereof.

' *My invention relates to car 'parts and is I of 'a rolled section, and Fig. 5 indicates the manner of shaping this section to the'proper particularlyv concerned with the production of peculiar forms-of rolled sections, adapted for use astruck bolsters, truck side frame, car sills axid the like. a

The object of the invention is the provision of a section :of this character which may be economically manufacturedand will be unusually strong in proportion. to 1ts weight and the amount of material.

In the accompanying drawings the several views illustrate. the preferred forms of the rolled section from which the various car parts may be manufactured, and also indlcate the manner in which said section may be brought to proper form.

Figure 1 1s a perspective view of a sectlon particularly adapted for the manufacture of car bolsters- Figs. 2 and 3 illustrate the steps in the shaping of the section shown in Fig. l to the proper form.

Fig. 4's an end view of a modified form form.

Figs. 6 and 8 are end'views offurther modified-forms of rolled sections and Figs. 7 and 9 illustrate the sections of Figs. 6 and 8 respectively, shaped to proper form;

-Fig. 10 is a perspective View of another modified form of section; Fig. 11 illustrates the manner of shaping the section shown n Fig. 10 to proper form.

Figs. 12,- 14 and 16 are end views respectively, of further modifications of the sections; Fig. 13 illustrates the manner of shaping the section of Fig. 12 to proper form;

Fig. 15 illustrates the manner of shaping the section of Fig, 14; and Fig. 17 the manner ofshapingthe section in Fig. 16, and;

Fig. 18 .illustrates the manner of use of the section Fig. 17. Fig. 19 is an elevation-o the parts shown in Fig. 18. i

Referring to Figs. 1, 2 and 3, the section here illustrated comprises a base .web 1, ex-

tending completely'across the section, and

having a pair of flanges 2 formed on one side can. PART.

opposite side directly opposite the flanges 2. On the same side of the web of the flanges 3 a are flanges Hand 55 The base web 1 extends beyond the outer flanges 55 forming lateral extensions 6--6 in the completed sections. This section may be readily rolled in the manner well known to those skilled in the art of metal rolling.

In Fig. 2 is illustrated the first step in the shaping of the section to car bolster form. By suitably arranged rolls the .web 1, together with the flangesfl: and 5, are bent or pressed upwardly along the innerlines of junction of the flanges 4 with the web. Thus the flanges 4 and 5 become lateral extensions of the web 1 and the portions of the web 1 between the flanges 4 and 5 become the side walls of the main channel member of the bolster in this case. At the completion of this 'step in the shaping operation, the lateral extensions 6 of the main web remain in line with the side walls of the chamiel.

In Fig. 3 these web extensions 6 are shown I as bent laterally, thus forming with the flanges 5 and the flanges 4 and adjacent portions of the main web, I beams which extend longitudinally. along each side of the com to the fish belly: shape illustrated in Fig. 2

.of the drawings, of my co-pending application, SerialNo. 800,879, filed November 13, 1913.

In Figs." 4 and 5 is illustrated a modified form of section for producing a truss member or bolster illustrated in Fig. 3.- In this case the section comprises a web 7 upper strengthening flanges 8 8, lower strengthening flanges 9-9', flanges 1O, 10, flanges 11,

- 11 and flanges 12, 12. Inthis casethe main web is bent or pressed upwardly along the line of junction of the flanges 1Q, 10 with the main .web, whereby I-beams comprising the flanges 10,10 which have now become lateral-extensions of the main web, flanges 11, 11 and flanges 12, 12, are immediately formed without the necessity of subsequently bending down the parts 12,'12corresponding to' the parts 6, 6 in-Fig. 3. as before described. The strengthening flanges 9, 9 may here also be sheared to produce the fish-belly structure heretofore described.

In Figs. 6 and 7 is illustrated an end view of a section and a transverse sectional view of a truss member or car part formed from said section. In this case the section comprises the main web 13, the upward strengtheningflange 14, the downward strengthening flange 15, the flanges 16, 16 flanges 17 17 and flanges 18, 18. shaped or pressed upv into the form illus-. trated in Fig. 7 as heretofore described.

A modifled'form of section illustrated in Fig. 8 comprises the main web 19, flanges 20 20, flanges 21, 21 and flanges 22, 22.

Fig. 9 illustrates the section shown in Fig. 8 shaped or pressed up to the form of a car part, the portion of the main web between the flanges 20, 20 and flanges 2O them selves becoming the base web of the car part, and this base web, together with the portions thereof bent upwardly, and the flanges 21 and 22, become the I-beams extending longitudinally along each side of the completed structure. 1

In Fig. 10 the modified form of section comprises the main flanges 23, strengthening flanges 24, 24, strengthening flanges 25, 25, flanges 26, 26and flanges 27, 27. This section is bent or pressed upwa'rdl in a manner similar to that described or the various sections whereby the main web 23 V described, whereby the portion of the main web 28 between the flanges '31, 31, together with said flanges 31, 31, become the base web of the structure, the portions of the main web together with the flanges 32, 32 forming with the flanges 31, 31, channel members extending along each side of the completed structure.

The section shown in Fig. 14 consists of the main web 33, central strengthening flanges 34, 34, flanges 35, 35, and flanges 36, 36. This section is shown as bent to structural form in Fig. 15 as heretofore shown.

In Fig. 16 the section comprises the main web 37, flanges 38, 38 and flanges 39, 39. This section is shown bent to structural form in Fig. 17.

The sections illustrated in Figs. 1 to 7 This section is also strength longitudinally of the bolster.

and Figs. 10 to 15 are particularly, though not exclusively, adapted for use in car bolsters, although it is obvious that they may be also used in many instances as car sills, or any other relation where truss members are desirable. p

The sections illustrated in Figs. 8 and 9,.

16 and 17, are particularly, though not exclusively, adapted for use as side frames or.

ag-car sills. The section in Figs. 16 and 17,

however, may also beadvantageously employed in car bolsters as illustrated in Figs. 18 and 19. In said figures, the section is shown in reversed position or upside-down,

in which the main web 37 becomes the upper web of the carbolster and the lateral channel members become the main truss members.

and moreover, the flanges 39, 39 afford convenient means for. securing a -fish-belly strengthenin member to the main bolster section. This fish-belly member may be formed by pressing it or shaping a flat plate of rolled steel, thus providing the same with lateral flangesf40, adapted to be riveted to the lateral flanges 39, as at 41. The central portion of this plate is pressed or shaped to form the fish-belly structure 42 for the purpose'of imparting the greatest possible It will be noted also that strengthening flanges 38, 39 and 40 form a peculiarly strong construction to resist lateral twisting strains on the bolster.

, It will be noted that in all the forms of the invention described, the structures consist essentially and in the first instance, of a simple rolled section of steel of a form which may be readily and easily rolled in a manner well known to those skilled in, this art.

. The shaping of the section consists of mere pressing or bending operations, which bring the rolled shape into proper structural form. In each instance it will also be noted that the truss member or structure so produced, includes in all cases channel members extending longitudinally along each side of the structure thus affordin great strength for the resisting laterally o twisting strains.

In the form shown in Figs. 1 to 9 incluferred embodiment of the invention, it is to i be understood that the same may be altered 25 bent longitudinally to cause said flanges to in details and arrangements of parts within. the scope of the appended claims.
